Product Code:SAE J286
Title:SAE No. 2 Clutch Friction Test Machine Guidelines
Issuing Committee:Automatic Transmission Friction Standards Committee
Scope:This SAE Recommended Practice is intended as a guide toward implementation of a standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use.The SAE No. 2 friction test machine is used to evaluate the friction characteristics of automatic transmission plate clutch with automotive transmission fluids. It can also be used to conduct durability tests on wet friction systems.【英文标准名称】:Non-destructiveTest;UltrasonicMethodofTestingCladdings,ProducedbyWelding,RollingandExplosion
